我想使用的代码共享图像： 

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri imageUri = Uri.parse("http://stacktoheap.com/images/stackoverflow.png");
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(sharingIntent);

我做了一个按钮，拨打上面的代码。 份额的意图打开，但如果我点击“通过彩信分享”我：“不能将此图片添加到您的信息”。 如果Facebook我只拿到了一个文本区域，没有我的照片。

Answer 1:

@的eclass的回答改编版，它不需要使用的ImageView的：

用毕加索的url加载到一个位图

public void shareItem(String url) {
    Picasso.with(getApplicationContext()).load(url).into(new Target() {
        @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("image/*");
            i.putExtra(Intent.EXTRA_STREAM, getLocalBitmapUri(bitmap));
            startActivity(Intent.createChooser(i, "Share Image"));
        }
        @Override public void onBitmapFailed(Drawable errorDrawable) { }
        @Override public void onPrepareLoad(Drawable placeHolderDrawable) { }
    });
}

位图转换成乌里

public Uri getLocalBitmapUri(Bitmap bmp) {
    Uri bmpUri = null;
    try {
        File file =  new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
        FileOutputStream out = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
        out.close();
        bmpUri = Uri.fromFile(file);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return bmpUri;
}


Answer 2:

我使用这些代码从本教程 

        final ImageView imgview= (ImageView)findViewById(R.id.feedImage1);

                Uri bmpUri = getLocalBitmapUri(imgview);
                if (bmpUri != null) {
                    // Construct a ShareIntent with link to image
                    Intent shareIntent = new Intent();
                    shareIntent.setAction(Intent.ACTION_SEND);
                    shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
                    shareIntent.setType("image/*");
                    // Launch sharing dialog for image
                    startActivity(Intent.createChooser(shareIntent, "Share Image"));    
                } else {
                    // ...sharing failed, handle error
                }

然后添加到您的活动

 public Uri getLocalBitmapUri(ImageView imageView) {
    // Extract Bitmap from ImageView drawable
    Drawable drawable = imageView.getDrawable();
    Bitmap bmp = null;
    if (drawable instanceof BitmapDrawable){
       bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
    } else {
       return null;
    }
    // Store image to default external storage directory
    Uri bmpUri = null;
    try {
        File file =  new File(Environment.getExternalStoragePublicDirectory(  
            Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");
        file.getParentFile().mkdirs();
        FileOutputStream out = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
        out.close();
        bmpUri = Uri.fromFile(file);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return bmpUri;
}

然后添加您的应用程序清单

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />


Answer 3:

你需要使用一个本地文件。 像这样： 

      Uri imageUri = Uri.parse("android.resource://your.package/drawable/fileName");
      Intent intent = new Intent(Intent.ACTION_SEND);
      intent.setType("image/png");

      intent.putExtra(Intent.EXTRA_STREAM, imageUri);
      startActivity(Intent.createChooser(intent , "Share"));

如果图像是远程服务器上首先下载到设备。



Answer 4:

大量的琢磨后，这里是我发现是为我工作的代码！ 我认为这是代码最简单的版本，以实现利用毕加索给定的任务之一。 有没有需要创建一个ImageView的对象。 

            Target target = new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                bmp = bitmap;
                String path = MediaStore.Images.Media.insertImage(getContentResolver(), bmp, "SomeText", null);
                Log.d("Path", path);
                Intent intent = new Intent(Intent.ACTION_SEND);
                intent.putExtra(Intent.EXTRA_TEXT, "Hey view/download this image");
                Uri screenshotUri = Uri.parse(path);
                intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
                intent.setType("image/*");
                startActivity(Intent.createChooser(intent, "Share image via..."));
            }

            @Override
            public void onBitmapFailed(Drawable errorDrawable) {

            }

            @Override
            public void onPrepareLoad(Drawable placeHolderDrawable) {

            }
        };
        String url = "http://efdreams.com/data_images/dreams/face/face-03.jpg";
        Picasso.with(getApplicationContext()).load(url).into(target);

在这里，BMP是一类级别的位图变量和URL将是动态的互联网网址到您的共享画面。 此外，而不是保持代码的onBitmapLoaded（）函数内部共享，也可以保持内部的其他处理功能和后来从onBitmapLoaded（）函数调用。 希望这可以帮助！



Answer 5:

试试这个： 

new OmegaIntentBuilder(context)
                .share()
                .filesUrls("http://stacktoheap.com/images/stackoverflow.png")
                .download(new DownloadCallback() {
                    @Override
                    public void onDownloaded(boolean success, @NotNull ContextIntentHandler contextIntentHandler) {
                        contextIntentHandler.startActivity();
                    }
                });

Answer 6:

首先，你需要在滑行加载图像。 然后，你可以分享给任何地方。 代码从滑行加载图像（图像保存到存储，以后可以将其删除）。 

Glide.with(getApplicationContext())
 .load(imagelink)\\ link of your image file(url)
 .asBitmap().skipMemoryCache(true).diskCacheStrategy(DiskCacheStrategy.NONE)

 .into(new SimpleTarget < Bitmap > (250, 250) {
  @Override
  public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {


   Intent intent = new Intent(Intent.ACTION_SEND);
   intent.putExtra(Intent.EXTRA_TEXT, "Hey view/download this image");
   String path = MediaStore.Images.Media.insertImage(getContentResolver(), resource, "", null);
   Log.i("quoteswahttodo", "is onresoursereddy" + path);

   Uri screenshotUri = Uri.parse(path);

   Log.i("quoteswahttodo", "is onresoursereddy" + screenshotUri);

   intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
   intent.setType("image/*");

   startActivity(Intent.createChooser(intent, "Share image via..."));
  }

  @Override
  public void onLoadFailed(Exception e, Drawable errorDrawable) {
   Toast.makeText(getApplicationContext(), "Something went wrong", Toast.LENGTH_SHORT).show();


   super.onLoadFailed(e, errorDrawable);
  }

  @Override
  public void onLoadStarted(Drawable placeholder) {
   Toast.makeText(getApplicationContext(), "Starting", Toast.LENGTH_SHORT).show();

   super.onLoadStarted(placeholder);
  }
 });


Answer 7:

   share.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                int permissionCheck = ContextCompat.checkSelfPermission(SingleProduct.this,
                        Manifest.permission.READ_EXTERNAL_STORAGE);

                if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
                    Log.e("MainActivity ", "P granted");

                    bmpUri = getLocalBitmapUri(imageView);

                } else {
                    ActivityCompat.requestPermissions(SingleProduct.this,
                            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
                }
            } else {
                Log.e("MainActivity", "Lower Than MarshMallow");
                bmpUri = getLocalBitmapUri(imageView);
            }

            if (bmpUri != null) {
                // Construct a ShareIntent with link to image
                Intent shareIntent = new Intent();
                shareIntent.setAction(Intent.ACTION_SEND);
                shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
                shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                shareIntent.setType("image/*");
                startActivity(Intent.createChooser(shareIntent, "Share Image"));
            } else {
                Toast.makeText(SingleProduct.this, "Sharing Failed !!", Toast.LENGTH_SHORT).show();
            }
        }
    });

 public Uri getLocalBitmapUri(ImageView imageView) {
    Drawable drawable = imageView.getDrawable();
    Bitmap bmp = null;
    if (drawable instanceof BitmapDrawable) {
        bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
    } else {
        return null;
    }
    Uri bmpUri = null;
    try {
        File file = new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
        FileOutputStream out = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
        out.close();

       bmpUri = Uri.fromFile(file);


    } catch (IOException e) {
        e.printStackTrace();
    }
    return bmpUri;
}

//for oreo add below code in manifest under application tag

 <provider
        android:name=".utility.GenericFileProvider"
        android:authorities="${applicationId}.your package 
     name.utility.GenericFileProvider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>

create class that extends FileProvider

public class MyFileProvider extends FileProvider {

}

for oreo add this code

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            bmpUri = FileProvider.getUriForFile(this, 
      this.getApplicationContext().getPackageName() + 
    ".your package name.GenericFileProvider", file);
        } else {
            bmpUri = Uri.fromFile(file);
        }

finally add provider_paths.xml in res/xml 

   <paths xmlns:android="http://schemas.android.com/apk/res/android">
   <external-path name="external_files" path="."/>
   </paths>

就这样



Answer 8:

通过使用createchooser你可以做到这一点， 

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(path);

sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));

注册在意向

如果你想上市的应用程序时，这个意图是所谓的，那么你必须在你的manifest.xml文件添加一个意图过滤器

 <intent-filter>
 <action android:name="android.intent.action.SEND" />
 <category android:name="android.intent.category.DEFAULT" />
 <data android:mimeType="image/*" />
 </intent-filter>
